Cast Iron Engine Block vs Aluminum: Which is Better ...
· Cast iron blocks have better heat retention and they can stand the negative effects of high temperatures – cast iron blocks are less likely to suffer from over-heating problems compared to aluminum. Under high temperatures, aluminum can be warped which can damage the longevity of the engine block. Aluminum is easier to weld compared to iron.
